What is the mainstream thought of China's traditional culture?

There are various traditional cultures in China, but if we want to introduce a mainstream, we must start from the "exclusive respect for Confucianism" of Emperor Wu of Han Dynasty, and Confucianism will become the official orthodoxy, ruling China society for two thousand years. Therefore, to study China's traditional cultural thoughts, we must first understand the mainstream thoughts of Confucianism-loyalty, filial piety, courtesy, benevolence, wisdom and courage. Of course, many of these are aimed at maintaining feudal orthodoxy and imperial patriarchy, but Confucianism has two very important points-benevolence and courtesy. Benevolence can be regarded as a kind of great love in human nature, while courtesy is the virtue of self-cultivation.
